Обсуждение: how to parse an proargtypes array?
Hi, first off all thank to the people that took the time to reply to my message,
Unfortunately I do have another question to ask:
I'm trying to find out all the argument type that a user-defined function required, I used this query, select proargtypes from pg_proc where proname = 'add_movie'; but it gives me an oidvector array 1043 23 1043 1043 1043 1015 1015 1015 1182 1015, is there a query to parse this and give me a list of type.
thanks

Perhaps the regprocedure output converter will help you. Forget
proargtypes, just cast the function's OID to regprocedure.
If you really want to deal with the individual function argument type
OIDs, regtype would help with converting those to useful text; or see
format_type().
